CARBURETER.

Specification of Letters Patent.

Patented dan. 16, 191'?.

Application filed June 12, 1915. serial No'. 33,680.

To all whom t may concern Be it known that I, GEORGE E. RIBLET, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have'invented new and useful Improvements in Carbureters, of which the following is a specification.

This invention relates to carbureters and consists in certain improvements in' the construction thereof as will be hereinafter fully described and pointed out in the claims.

The invention is illustrated in the accompanying drawings as follows Figure 1 shows a side elevation of the carbureter. Fig. 2 a section on the line 2-2 in Fig. 5. Fig. 3 a section of the air valve lever and its connection. Fig. 4 a section on the line 4-4 in Fig. 2. Fig. 5 an end elevation, partly in section, on the line 5-5 in Fig. 2. Fig. 6 a section on the line 6-6 in Fig. 1. Fig. 7 a plan view of the carbureter.

1 marks the body of the carbureter. This contains the fuel chamber 2. It is formed by the walls of the body and is closed by a bottom plate 3 which is secured tothe bottom of the body in any convenient manner, as shown by screws (see Fig. 4). A. fuel inlet 4 extends through the plate 3 and is controlled by a needle valve 5. The needle valve 5 has a slot 6 in its stem in which the end 7 of a float lever 8 extends. The valve is guided by a tube 5a extending upwardly from the bottom plate 3. The float lever is journaled on a pin 9 carried by the post 10 extending upwardly from the plate 3. The float 11 is mounted on the end ofthe lever 8.

The mixing chamber 12 is formed above the fuel chamber. It extends on an incline, the bottom wall 13 of the mixingchamber being inclined and forming a vaporiz'ing wall for the carbureter. The wall 13 extends from the fuel inlet 14. This fuel inlet is in the form of a horizontal slot extending across the bottom of the inclined wall 13. The width of this slot is controlled yby a valve 15 having the ways 16 and 17 leading from and to the center of the valve. The way 17 is adapted to come into register with the way 18 leading to the fuel chamber.

To give a proper amount of fuel for the ordinary carbureter the width of the fuel slot is necessarily very small. With this vwidth there is a tendency for bubbles to form along the slot forming to some extent a seal or obstruction to the flow of fuel through the slot. This is corrected by placing vent pipes 19 at the end of the slot.

VAir is admitted through an opening 20. The amount of air is controlled by the air valve 21 arranged in the valve body 22. T ie air valve is cylindrically shaped and rocks as it is opened and closed. The valve vhas the ways 23 and 24 leading to and from the valve. The way 24 delivers the air to a wall 25 in a direction to sweep the fuel-slot 14 and the inclined wall 13 of the mixing chamber.

The throttle valve 26 similar in shape to the air valve is arranged in a body 27. lt has the ways 28 and 29 leading to and from the valve, the way 28 leading from the mixing chamber and theway 29 to the separating chamber 30. The separating'chamber 30 has an inwardly extending lip 31 which catches any fuel in liquid form and carries it beyond the discharge opening 37, the fuel being deposited in the pocket 32. An opening 33 extends from the pocket 32. A valve 34 controls the opening 33, the valve having a way 35 adapted to be brought into register with the opening 33 and the opening 36 leading to the atmosphere. The valve 34 and this opening has a function in addition to that of draining the pocket 32. Air may be admitted to the carbureter after it has passed the throttle valve. By adjusting this it can be readily ascertained whether the adjustment of the valves is given a proper' amount of air and if it is found by the use of the valve 34 that additional air is desired this may be then accomplished by a readjustment of the air valve and throttle valve or fuel valve. v The mechanism for operating the valves is as follows -The fuel valve has a lever 38` at its end. This lever has the ends 39 which extend between the shoulders 40 on a. screw 41. The screw 41 extends through a lug 42 on the side of the carbureter body. The screw is provided with a handle 43 by means of which the fuel valve may be nicely adjusted thus varying the width of the slot 14.

The throttle valve has a plate 44 at its end from which extends the gear segment 45. The gear segment 45 meshes a segment 46. The gear segment 46 is mounted on a stud 47 at the top of the carbureter. A lever 48 extends from the gear segment 46 and the throttle rod is secured to the lever 48. It will be readily seen that as the lever 48 is thrown in one direction-or the other the throttle valve is opened or closed through the action of the gear segments. The minimum opening of the throttle may be adjusted by a screw 49 which extends through a lug 50 in the side of the carbureter.

A lever 51 extends Vfrom the-air valve at the outside of the valve body. It` has a swivel stud 52 secured to it through which the screw 53 extends. rlhe screw 53 has a shoulder 54 which abuts against a rounded end 55. A washer 56 also abuts the rounded end 55 at the opposite side of the shoulder 54. A spring 57 is arranged around theV screw stem and exerts pressure on the washer 56. A handle 58 is provided for the screw by means of which it may be adjusted. A lever 59 is arranged on the rounded end 55 and is carried by a plate 60. The plate 60 is journaled on a screw 60a, the screw being secured in the end of the air valve. A lever 61 extends from the plate 60 and is provided at its end with a slot 62 which slot registers with a slot 63 in an arm 64 on the plate 44. These slots with the screw 49 in its normal adjustment are in register. in the slot 62 and the nut 66 is screwed on the end of the block, the nut 66 forming a sliding lit with the slot 63. A screw 67 operates in the block 65. The screw extends through an enlarged perforation in a projection 68 extending from the plate 60. Shoulders 69 are arranged on the screw stem at each side of the projection 68.

It will be readily seen that by the operation of the screw 67 the block 65 may be moved along the slots 62 and 63 so as to vary the point of connection between the lever 61 and the lever 64. These levers form an operative connection between the throttle valve and the air valve. By varying the point of connection through the movement of the block the relative movement of the air valveY to the throttle valve may bevaried so'that this may be adjusted to variations in fuel and airV conditions.

AV knuckle joint 70 is arranged on the end of the screw 67 and a rod 71 extends through the knuckle connection and is carried to a convenient point for adjusting the sliding block 65.

Y Any suitable connection may be made to Y through the rounded end 55 compresses the spring 57 Yand thus permits the momentary closing of theV air valve for the purpose of priming. Y Y j A lever 72 is provided for the valve 34 by means of which it may be readily operated.
